As AAA said in a comment beside me it isn't so much that I expect it would predate a space elevator. Simply that it is possible with current tech rather than still waiting on additional moderately likely breakthroughs like long chain carbon nanotube tether.

Also there are plenty of options to have the vast majority of the material be from space and not the surface since the core idea is a metal like copper being spun above orbital speed after being made into a full loop then used for the mag lev to keep at ground speed. There are absolutely a lot of astroids that might allow for that.

Constructing an Orbital ring and then using that to get a form of space elevator built.

Totally possible to build with our current technology but the cost if we do it pre space elevator or similar is pretty insane.

Building a ring let's us basically have a stable space side anchor at low earth orbit instead of geo sync ish like you need for a normal space elevator to match ground speed.

Even more fun is cost for additional rings drops massively and you can build them in different orientations you can get space elevators to rings without having to be on the equator.

Last and my favorite part is the possibility of having literally trains that go up to a ring cross an ocean and go back down. Wouldn't be faster than planes but massively better cargo capacity and efficiency as well as comfortable for passengers.

Absolutely disagree on this. There is no fundamental reason software must have bugs. However old systems can be their own technical debt because of things like the hardware no longer being produced and therefore unable to be directly repaired if it breaks from age.

This leaves either reprogramming for a modern device or things like emulation which can create/surface bugs that weren't present before.

The most extreme example I have heard of (sadly couldn't quickly find a link for it) was a disorientation simulator for pilot training that had zero software issues in several decades of use and when the hardware failed they replaced it with an FPGA in a modern system that ran all the old code 1 for 1. PDP stuff originally I think.

Additional edit - I'll add that "bug free" software is insanely rare in reality and nearly but not quite impossible to create in practice. I can't say the software didn't technically have bugs but if multiple decades of use didn't have them show up in practice it is functionally bug free.

I feel this. Both in terms of driver engagement safety and in how much I loathe traditional automatic transmissions. Still stuck owning one in one of the two vehicles I have at the moment but only because it was all I could afford for the second of two vehicles large enough to fit all my kids.

I have had several manual transmission vehicles and the other current one is a PHEV and one of the rare models that is a series hybrid so it drives like a true EV.

While you are most definitely correct his parents wouldn't do that; schools back then absolutely did enforce that and he clearly did still go through school.

Ok that is one of the most adorable things I have ever seen.

Sadly I don't but would also like to see it if it is available.

Sounds like we would have to build satellites with shades that would be selectively turned off and on as needed and only for specific parts of the globe like the overheating cities. Might be able to have some interesting effects forcing weather patterns that way.

However as you say none of that helps the ocean acidification and that is terrifying.

Right you are I missed that. So comets at least aren't workable.

Yea I agree.

I can't remember if the Brian Herbert books or just my own trying to resolve that in my own head but I feel like I ran across an attempt at resolving that saying that even world sized computer systems of the thinking machines still had worse results than the guild navigators since the navigators weren't actually computing routes so much as using dune's bizarre mental abilities like telepathy etc. to directly reach out and connect to the destination.

Actually that could even be from one of the movies and TV. Blurry memory on it.

Love Dune overall and very glad it is in the world of well known stories now with things like the warnings against charismatic leaders etc. but it still definitely has its flaws.

Both agree but have to remember there are a couple other things in play.

One is that afterwards they have mentats so the ultra wealthy have access to something at least somewhat equivalent in function.

Second, while general AI (and arguably even general purpose CPUs) are banned they clearly have ultra advanced fixed function computing devices at ultra low prices everywhere. The Freman make still suits in their cave cities that are basically magic by modern standards so access to advanced fixed function computing and materials science is clearly essentially universal.

Kinda. The exact quote for it being lowered down without heating up from reentry is "the added ice would cool the water down by only about a millionth of a degree" But yea essentially useless in the big scheme of things.

The ice would be massively better used in space habitats or terraforming other places.

In a strictly technical sense if you source ice in space from something like a comet and bring it down slowly with something like a space elevator it would help a tiny bit. However the amount of effort would be much better spent on either fixing things we are doing or going for one of the crazier but valid options like building satellites that shade something like 1-2% of sunlight etc.

That is actually a very valid reason why it wouldn't be an in use commercial product at this point.

I'm still fairly sure that can be solved but it is a much higher bar to clear especially to do so and keep it within a cost that isn't insane.

We get high power electronics in things like rockets and jets and tanks etc. so again I'm sure it is possible eventually. It could easily be a price so high that it doesn't happen without government mandates or that artificial fuels from bio or carbon capture end up still lower priced than what it takes to make the tougher electronics.

They do make induction models that are curved specifically for woks. Don't know the right places to search to see if restaurant power level models exist but don't see any electrical reason it couldn't be done.

Very good list in my opinion and definitely matches my memory from learning about Andrew Jackson in the past.

I agree that Trump is no Hitler. While by some magic the crowds at his events like him he absolutely isn't the orator Hitler was among a lot of other differences.

However I still say the overall party/political movement he is head of is extremely fascist and incorporating a lot of Nazi elements. The flip to that is that the Nazis got a lot of stuff from the USA and the Nazis loved our racist policies in the 30s and our history of doing things like the westward expansion and what that did to the native people.

My family (wife and multiple kids) oddly enough have access to both this and Minecraft and actually prefer Luanti most of the time.

Try Lego Masters from other regions. I'm guessing you are watching the USA version and I know my kids have enjoyed the Australian version way more. All a matter of taste of course in what works for you especially in terms of something like a show host.

Nope what fell out of the sky was the wizard holding the scrolls that give you an insanely high magic jump that kills you in impact on the other end if you don't prepare.

The boots of blinding speed and worn by someone that is effectively blind when you meet them. Don't remember the name. Fun thing is you can just infinitely try sneaking around them and always keep gaining skill since they always fail their roll for if they see you which gives you the exp.

I hear people say all the time that it is perfect. It definitely has imperfections.

However while I will insist on it being imperfect it has still been my number one favorite game for at least two decades.

It is easily the closest to perfect I think you could possibly ask for with the hardware limitations and the fact that teams don't have magical infinite time or budgets. Anyone with even a slight interest in RPGs should play it.

Plus it gave us the musical career of Yasunori Mitsuda
